More features

• Powered by 16 high-power 3030 LED chips, each 3157 switch back led bulb offers brilliant white and amber brightness while consuming less power. Paired with an HD glass lens for stronger, more focused light penetration, ensuring superior visibility and safer driving in all weather conditions.
• White for DRL or parking lights; Amber yellow for turn signal lights. The 3157 led turn signal bulbs flashes "amber-off-amber-off" instead of " amber-white-amber-white", much easier to see. ( Most switchback bulbs in the market flash amber-white-amber-white )
• Designed with a wide 9V–18V DC input range and a built-in intelligent constant-current IC driver, this 4157 led turn signal bulb ensures stable operation without causing digital or VHF radio interference. The aluminum circuit board further enhances performance through highly effective heat dissipation.
• Plug-and-play installation with no polarity design ensures a hassle-free setup, compatible with both standard and CK sockets. Fit socket 3157, 3157A, 3057, 3155, 3157NA, 3357, 3457, 3457A, 4057, 4114, 4157, etc
• Note: These 3157 switchback led turn signal bulbs are designed specifically for dual-function lights that combine parking/city light and turn signal functions into a single bulb. A 50W 6-ohm load resistor or an upgraded flasher relay may be required to prevent hyper flash or non-blinking issues. We've included the resistors in the package, so you'll have them on hand if required.
